Abstract: PROBLEM TO BE SOLVED: To provide a method for effectively supplying main gas into a molten metal pool part, particularly useful to use in an electric arc furnace. SOLUTION: In this method, the combustion of fuel with secondary oxygen is used to form the glame envelope around the flow of the main gas for protecting from being accompanied with the surrounding gas at the time of passing through the head space of the furnace. This method can hold the original power to the plactical degree at the time of pouring the gas into the head space and thus, the gas can be flowed into the further in the safe distance from the molten metal surface, and further, substantially full invasion onto the molten metal can be achieved.

Abstract: A system for combusting difficult to combust fluid such as waste fluid (8) wherein fuel (1) and gaseous oxidant (4) combust in a hot combustion gas chamber (3) to form a hot combustion gas mixture which is accelerated to a high speed and at a steady, i.e. nonpulsing, flow is then used to atomize and then combust the fluid.

Abstract: The invention comprises a reactor having a source of a first hot reactant gas, a mixing chamber in which said first hot reactant gas mixes with a second reactant gas to form a reactant gas mixture, but wherein substantially no reaction takes place and a reaction zone wherein said mixture undergoes vapor phase reaction. A process for using the reactor is also disclosed.

Abstract: A METHOD FOR INTRODUCING GAS INTO A LIQUID WHEREIN A GAS STREAM IS EJECTED FROM A LANCE SPACED ABOVE THE LIQUID SURFACE AND DIRECTED FROM THE LANCE ONTO THE LIQUID SURFACE. THE GAS RETAINS SUBSTANTIALLY ALL ITS ORIGINAL JET AXIS VELOCITY WHEN IT CONTACTS THE LIQUID SURFACE, AND SUBSTANTIALLY ALL OF THE GAS PENETRATES THE LIQUID SURFACE AND IS INTRODUCED INTO THE LIQUID. PREFERABLY THE GAS STREAM IS SURROUNDED BY A FLAME ENVELOPE RUNNING FROM THE LANCE TO THE LIQUID SURFACE, WHICH SHIELDS THE GAS FROM AMBIENT GAS ENTRAINMENT. THE GAS STREAM PREFERABLY FORMS A GAS CAVITY WITHIN THE LIQUID HAVING A DIAMETER SUBSTANTIALLY THE SAME AS THE DIAMETER OF THE GAS STREAM AS IT IS EJECTED FROM THE LANCE.

Abstract: A system for establishing a single coherent gas jet from a plurality of initial gas jets ejected from a single lance wherein the initial gas jets are themselves coherent, are angled inward, and are surrounded by a flame envelope. The initial coherent gas jets merge to form a single coherent jet and the gases of the initial gas jets do not substantially interact within this single coherent jet for the length of the resulting single coherent gas jet.

Abstract: A system for providing gases (1) into an injection volume in one or more coherent gas jets (30) proximate to one or more turbulent gas jets (32) wherein a coherent gas jet is formed in a forming volume (5) with a flame envelope (31) prior to passage into the injection volume into which the turbulent gas jets are directly passed.
